CompoundPropertyModel constructor allows misuse of model object

Right now the constructor of CompoundPropertyModel is as follows:

/**

• Constructor
  *
• @param object
• The model object, which may or may not implement IModel
  */
  public CompoundPropertyModel(final Object object) { target = object; }
  
  which allows users to do something like:
  
  new CompoundPropertyModel<XXX>(new YYY());
  
  without generating a compiler error. Would it make sense to replace
  this constructor by two constructors...
  
  /**
  * Constructor
  *
  * @param object
  * The model object
  */
  public CompoundPropertyModel(final T object)
  { target = object; }

/**

• Constructor
  *
• @param object
• an instance of IModel<T>
  */
  public CompoundPropertyModel(final IModel<T> object) { target = object; }

at least on 1.5?
